You don't need the headers, but they look cool. With a stock setup, 1 and 6 don't really run poorly. Just look at the plugs. I did notice that my truck seemed to idle a little more smoothly after putting the offy on. That, however, could be just because of the time I spent getting everything happy, and just thinking it runs better after all that work?
